SULPH'URING MACHINE.

Application filed June 17, 1925. Serial No. 37,687.

My invention relates to a sulphuring ma- 1 chine, and more specifically to the device for machinery. The pulverized sulphur is usu'-' ally shipped in sacks, and owing to certain adhesive qualities, it sometimes forms into chunks so that 1t Wlll not feed uniformly through a small aperture. To overcome this difliculty I have invented a mechanism which powders the sulphur within the hopper. as it drops adjacent to the bottom ofthe hopper.

ihe object I have accomplished is the pulverizin of the sulohur re arator to dust- 1 ing it through a dusting deviceand a uniform feeding of the sulphur dust through the dis- .charge opening in the hopper.

These objects are accomplished by means of the device hereinafter described and illustrated on the accompanying drawing, in

" which Figure 1 is a top view of thedusting machine with parts cut away showing the pulverizing device. Figure 2 is a fractional side view of the machine showing the hopper in section. Figure 3 is a top view of the rotary knife adapted to pulverize the sulphur. Figure 4 is a side view ofthe device shown in Figure 3.

In said drawing 5 is the frame of a sulphuring machine carried on traction wheel 6. The axle '7 to which the traction wheels are attached is adapted to rotate with the wheels, and carriesa large drive wheel 19. An auxiliary shaft 9 carries a small gear 21, which is aligned with large gear 19 so that on the rotation of the gear 19 the motion is communicated to gear 21. Gear 21 rotates loosely on shaft 9, and by means of a clutch 23 gear 21 can be made to revolve shaft 9.

I also carries rigidly attachedthereto a gear "10*, which rotates a gear 8 adapted to run loosely on shaft 7 by means of a belt 10. A

connections 46 and 47. Shaft 9 carries a Shaft 9 beveled gear 11 which act uates a similar gear 12. Gear 12carries a shaft13 which rotates.

an agitator A. Agitator A consists of a plurality of blades 30 which rotate on a come .ion plane, and one or more arms 31, which extend above the plane covered by blades 30. I have provided a hopper 15 having av bottom 16, which is positioned on the frame of the vehicle so that the blades 30.will rotate directly above and on aplane with the bottom and within the hopper and the arms 31 will rotate on the plane of a cone. A hole 40 is made through the bottom of the hopper in a position whereby the blades 30 when rotating press directly over said hole and a lead from said hole enters the pipe 44.

It will thus be noted that when the vehicle is moved the traction wheels 6 will revolve the agitator A by means ofthe train of gears hereinbefore described, and also will make the fan function to blow air through tube 44 and through hose connections 46 and 47.

When the hopper has sulphur therein the agitator A tends to keep the opening '40 clear of lumps by cutting and pulverizing any lumps of sulphur which may be in the hopper, and which are adjacent to said opening,

and the arms 31 tend to draw the sulphur down toward theknives and toward the bottom ofthe hopper if gravity should fail to v properly function for that purpose and to break up the larger lumps For the purpose of'limiti'ng the size of hole 40,1 havearrangeda lid 41 .which can be moved to cover hole 40in whole or in'part by moving the foot lever 43 up or down, said lever being connected with the lid by a rod 42. Having described my invention, I claim as.- new and ask for Letters Patent: In a dusting'machine in combination with a hopper having a bottom and a discharge opening through said bottom,of an agitator consisting of a plurality of blades extending radially from a common center member, said center member being pivotally mounted and CLAUDE T. sPIVEYQ
